Hello all,

I want to add a small quantity of gel coat (like the volume of a coffee spoon) to fill in a small hole in my mould (UNI MOULD made), as Matt is doing in the bonnet video. 
He's talking about a wax addtive to stop the gel coat from being tacky, so what this additive exactly is, where can I find it (doesn't seem to be sold in the EC store), and which is the ratio to be mixed with the gel coat ?

Thank you guys BigGrin

Thanks a lot for the tricks Nimateck Wink

I tried with flash tape on top of it, but couldn't seal it perfectly, so the result is unsatisfying. I'll definitely try additives.
